Ask the angels to surround you, pray to god and ask him protect you from any evil souls or entities who are around you. Call on archangel Michael for protection and help. Call on archangel Raphael for healing. Don't just ask once and give up though, keep asking and envision yourself in a white light. Light a candle, burn incense, spread holy water if it makes you feel better. The angels are always with you though and they will fight this thing off if you ask for their help! I have had very negative entities around before as well and the angels are the only tool that truly get rid of them. Good luck!
